Drilling and chambering integrated device of constant-resistance large deformation anchor rod
The invention relates to the technical field of drill bits, in particular to a drilling and chambering integrated device of a constant-resistance large deformation anchor rod. The drilling and chambering integrated device of the constant-resistance large deformation anchor rod comprises a plurality of drill bits, and the multiple drill bits are distributed along a straight line; each drill bit comprises a rod part and a head part; the head parts are arranged on the end surfaces of the rod parts; the rod part of one drill bit is detachably connected with the head part of another drill bit, andaxle wires of the rod parts are coincided; and diameters of the head parts are sequentially increased along the straight line. According to the drilling and chambering integrated device of the constant-resistance large deformation anchor rod, drilling and chambering can be finished at a time, the construction process is relatively simple, it is ensured that axes of a drilling segment and a chambering segment are coincided, and the machining accuracy is improved.
本公开涉及钻头技术领域，尤其涉及一种恒阻大变形锚杆的钻孔扩孔一体化装置。该恒阻大变形锚杆的钻孔扩孔一体化装置包括多个钻头，多个钻头沿直线分布；各钻头包括杆部和头部；头部设于杆部的端面；一个钻头的杆部可拆卸地连接于另一个钻头的头部，各个杆部的中轴线相重合；各个头部的直径沿直线依次增大。该恒阻大变形锚杆的钻孔扩孔一体化装置能够一次性完成钻孔和扩孔，施工过程较为简单，且能够保证钻孔段和扩孔段的轴线相重合，进而提高加工精度。
